Q:how to declare a property of Byte[] in iOS? - ios

Question

I have a method which need receive a Byte[] :
In the .h file:
- (void)setPC1_APPKEY:(Byte[] )pC1_APPKEY;
In the .m file:
I want to own a Byte[] property to save it.
But when I declare the property like this:
#property (nonatomic, assign) Byte PC1_APPKEY[];
It shows error:property cannot have array or function type'Byte[]'
And so I set it to attribute like this:
{
Byte PC1_APPKEY[];
}
It shows error:Field has Incomplete type ‘Byte[]’
How can I get the Byte[] ? thanks.

you can use Pointer like this
#property (nonatomic, assign) Byte *PC1_APPKEY;
all files
.h
//
// ocViewController.h
// testTableViewHeader

#import <UIKit/UIKit.h>
#interface TestViewController : UIViewController
- (void)setPC1_APPKEY:(Byte[] )pC1_APPKEY;
#end
.m
//
// ocViewController.m
// testTableViewHeader

#import "TestViewController.h"
#interface TestViewController ()
#property (nonatomic, assign) Byte *PC1_APPKEY;
#end
#implementation TestViewController
- (void)viewDidLoad {
[super viewDidLoad];
NSString *testString = #"1234567890";
NSData *testData = [testString dataUsingEncoding: NSUTF8StringEncoding];
self.PC1_APPKEY = (Byte *)[testData bytes];
for(int i=0;i<[testData length];i++){
printf("testByte = %d\n",self.PC1_APPKEY[i]);
}
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)setPC1_APPKEY:(Byte [])pC1_APPKEY{
self.PC1_APPKEY = pC1_APPKEY;
}
#end
